Ray denies killing two men he was seen with, and eventually McGarrett figures out that he's searching for his kidnapped daughter. McGarrett teams up with Ray and uses the young man as bait, but learns the Chinese National who took the daughter sold her. Racing against time, Five-0 and Ray rescue the daughter from a shipping container. Meanwhile, McGarrett encourages Catherine to accept a civilian job with an ex-boyfriend as she musters out of the Navy.
